ELECTRIC VAPORIZING-GASKET.

Application filed April 7,

T 0 all whom it may concern:

Be it known that I, WILBER KUTSOHE, a citizen of the United States, anda resident of \Vestern, in the county of Saline and State of Nebraska,have invented certain new and useful Improvements in Electricvaporizing-Gaskets, of which the following is a specification.

My invention relates to improvements in fuel 'vaporizers and it consistsin the construction, combination and mode of application=substantiallyas herein described and claimed.

One of the foremost objects of the invention is to provide a gasket tobe clamped between the intake manifold and outlet ofthe carbureter,embodying an electric resistance disposed across the path of the fuel,to heat and vaporize the latter as it passes through.

Another object of the invention resides in the various ways by means ofwhich the resistance is supported in place.

Other objects and advantages will appear in the following specification,reference being had to the accompanying drawing, in which Fi ure 1 is acomposite perspective view showing the various parts of the lead type ofgasket for supporting the resistance element,

Fig. 2 is a plan view showing the insulation type of the gasket, and

Fig. 3 is a detail elevation illustrating the place occupied b thegasket between the manifold and car ureter.

Attention is first directed to that form of the gasket, or vaporizer,shown in Fig. 1. The three parts 1, 2, 3, go together, that is to say, 2and 3 are superposed on 1 when the gasket as a whole is clamped inposition between the flange of the intake manifold 4 and the similarflange of the carburetor 5.

The part 1 in this instance is made of lead. At one side there is aspace at each side of which the lead gasket is formed with vertical keys6, these almost a pearing as complete circles when viewed ii-om above.The purpose of this formation is to provide recesses at the points 7, sothat the insulating locks 8 may be firmly held in place when fitted,over the keys.

Similar'keys 9 are cast or otherwise rovided on the lead insert 10, itbeing obvious when these various parts are firml pressed together, ahomogeneous gasket is t e result. A binding post 11 is fitted on theinsert 10.

1921. Serial No. 459,278.

A resistance wire 12 spans the central opening. The ends of this wireare fastened in any convenient manner between the gasket 1 and itsinsert 10.

Current is let in at one side and conducted away at the other, theinsulating locks 8 preventing short circuiting. The wire 12 mayconceivably be made in shapes other than that shown, so that the fuelpassage is more thoroughly covered and the fuel is more evenlyvaporized.

The pieces 2 and 3 are of thin insulating material. They are necessaryto in turn prevent current escaping to the adjacent metallic flanges ofthe manifold and earbureter. These pieces are used both in connectionwith the lead type vaporizer gasket, and also the insulating type towhich attention is now directed.

In Fig. 2 the gasket 1 is made of insulation. Like the gasket in Fig. i,it has keys 6, recesses 7, locks 8 and keys 9 on an insert 10. In eachcase, the substance of the material is reversed, that is to say, 8 isnow lead and 10 in now insulation.

A binding post 11* is now fitted on a third insert 13 which is likewiseheld in place by keys the same as in respect to the locks 8 above. Theresistance 12 is stretched between the insert and the locks and againmay assume any shape desired.

The purpose of the invention will be easily understood. A gasket of somekind is usually employed where there is a likelihood of either a gas orliquid leaking. This likeli hood is present at the 'joint where themanifold and carbureter are fastened together. I

It is also desirable to heat the incoming fuel, and the presentinvention therefore serves two important purposes, 2'. e. to seal thejoint and heat the fuel.

Since heating the fuel produces better vaporization, the name vaporizinggasket appears most appropriate. It remains only to be said thatconsiderable novelty lies in the mode of makin the gasket either in oneform or another. t is intended that it shall be sectional, and thisbeing the case a reliable device must be employed for holding thesections together. This device appears in the shape of the keys andlocks, and it is to this feature that the clainis are largely directed.

While the construction and arrangement of the improved vaporizin gasketas herein described and claimed, is t at of a generally preferred form,obviously modifications and changes may be made without departing fromthe spirit of the invention or the scope of the claims.

I claim 1. A vaporizing gasket, composed of a body of insulating andconducting parts,

and insulating pieces laid above and below when the gasket is clampedbetween a manifold and carbureter and a resistance element containedwithin the gasket.

2. A vaporizing gasket, composed of a body comprising insulating andconducting parts, means keying them together, a resistance elementconnected between certain con ducting parts, and insulating pieces laidabove and below the body.

3. A vaporizing gasket, comprising a body out out at one side to leave aspace, keys formed on the ends, approximating a circle to producerecesses; an insert with similar keys, and locks fitted between theinsert and body, having openings to receive the keys and produce ahomogeneous struc' ture when all parts are fitted to ther.

4. A vaporizing gasket comprising a body having a central openingtherein and including conducting and insulating sections havinginterfitting connections to ermit of the disassembling of the body, an aresistance wire carried by those conducting sections separated by theinsulating sections.

5. A vaporizing gasket comprising a body including a plurality ofconducting and insulating sections having connections to secure themembers against displacement in the plane of the gasket but to permit oftheir displacement laterally with respect to the gasket, and aresistance wire carried by those conducting sections separated by theinsulating sections.

6; In combination, an intake manifold, a carbureter, and a vaporizinggasket interposed between the two and composed of insulating andconducting sections which are free to be disconnected from each otherwhen removed from between the manifold and carbureter, but locked ingasket formation when in applied position, and a resistance elementcarried by those conducting sections of the gasket which are separatedby insulatin sections.

7. n combination, an intake manifold, a carbureter, and a vaporizinggasket interposed between the two and including insulating andconducting sections arranged to define an opening in the gasket toeffect communication between the carburetor and manifold, said sectionsbeing so connected to each other as to permit disassembling thereof whenremoved from between the manifold and 'carbureter, but locked in gasketformation when in applied position, a resistance wire carried by thoseconducting sections separated by the insulating sections, and insulatingieces at the opposite sides of the gaskets aving openings therein toregister with the gasket opening.

8. A vaporizing gasket comprising a body formed of oonductln sectionsand insulating sections betweent e conducting sections, and a resistancewire carried by the conducting sections, all of said sections beingdetachably connected to each other to facilitate the application andremoval of the resistance wire to and from the gasket.

9. A vaporizing gasket comprisin a body formed of insulating andconducting sections, and head and socket connections between thesections to permit detachment thereof for the purpose described.

10. A vaporizing gasket comprising a body formed of insulating andconducting sections, a resistance wire carried by conducting sectionsseparated b the insulating sections, and head and soc et connectionsbetween the sections arranged to secure said sections inst displacementin the lane of the gas et for the ur so describedi WI B R KUTSCHE.
